Priorslee Balancing Lake06:20 – 09:25

(297th visit of the year)

Bird notes:
- I heard Canada Geese fly in but did not see them. Five seen later, perhaps not all of these were the birds I heard arriving.
- an adult Mute Swan flew in. Odd that while the residents were still here they were chasing visitors almost daily. Since the residents departed this is only the second time I have noted any here.
- a pair of Goosander visited briefly.
- the usual post 08:30 gull arrival was almost non-existent.
- two Great (White) Egrets were present some of the time.
- 13 Song Thrushes singing today.

The Flash
09:30 – 10:40

(291st visit of the year)

Bird notes
I was told that the Cormorant seen tied up in fishing line last week later flew in to the trees and in so doing became suspended with the fishing line wrapped around branches. It was rescued by Cuan Wildlife Rescue. Had it not become suspended I doubt Cuan would have been able to catch it. No Cormorants seen today.

Other bird notes:
- the number of Pochard seems to change on a daily basis. There were four quite obvious drakes today.
- with four drake Goosanders there was much chasing around though no flying.
- the milder weather encouraged several Great Tits to sing.
